Thomas,

Yeah you are right. However, since Future#get() does not throw TimeoutException we have to throw ExecutionException in cases where user sets timeout on tasks and calls Future#get(). Also we have to take into account timeout specified with task builder and Future#get(timeout,TimeUnit). The algorithm I would suggest is the following:

{code}

private V innerGet(long timeout, TimeUnit unit) throws ExecutionException, TimeoutException {
...
...
            long taskTimeout = getOwningTask().timeout();
            long futureTimeout = TimeUnit.MILLISECONDS.convert(timeout, unit);
            long actualTimeout = 0;
            if (taskTimeout > 0 || futureTimeout > 0){
               if(taskTimeout > 0 && futureTimeout == 0){
                  actualTimeout = taskTimeout;
               } else if (taskTimeout == 0 && futureTimeout > 0) {
                  actualTimeout = futureTimeout;
               } else if (taskTimeout > 0 && futureTimeout >0) {
                  actualTimeout = taskTimeout < futureTimeout ? taskTimeout : futureTimeout;
               }
            }
            if (actualTimeout > 0) {
               response = retrieveResult(f.get(actualTimeout, TimeUnit.MILLISECONDS));
            } else {               
               response = retrieveResult(f.get());
            }

...
}
{code}
